'9 Claims. (cram-e1) This invention more particularly relates to a container or drum which is closed on its chime by a removable head havingsecuring means for effecting afluid tight joint between the head and the chime;

Ano'bject of the invention is to provide an improved operating mechanism 'for the'securing band-of the removable head and container chime.

Another object of theinvention is in providing '-a splitv securingband for the heads and chimes of containers having an improved operating mechanism'therefor, carried by one end of the band and the "mechanism having detachable connectin'gineans for the other endof' the band. A further object of the invention is in providing a band sealing and locking devicewith an operating mechanism having'means which are cooperable to contract the band before the locking 'meansof the mechanism is effected.

Other and further'objects' will appear in the specification and be specifically pointed out in the appended claims, reference being had to the accompanying drawing, exemplifying the invention, and in which: 1

mechanism in a position of disengaging the links of the band from the locking pin. 1 Referring to the drawing, 1 indicates/the container or drum having the vertical wall 2, the up annularly .therearound for providing a bead 3 which constitutes the chime of the container. 5

A removable counter-sunk head 4 having a vertical wall 5 with a surrounding outwardly ex-( tending horizontal marginal flange 6, is provided for cooperation with the container chime, and formed in the wall 5 of the head is an annular r groove '7 for the support of a sealing gasket 8. For securing the head4 to the chime after the container 1 has been filled, a split locking band 9 is provided, said band being of a channel shapein cross section and having the ends '10 and 11 adjacentthe split of the band, each of said ends hav-v ing an inwardly projecting horizontal portion 12 extending from the top side of the band, the per tion 12 of the end having a downwardlyextending part 13 which is of adepth to engage the counter-sunk parted of the head.

' Secured to the depending part 13 in straddling position thereto by the pin '14 are the ends of a' pair of links 15, the opposite ends of said links bearing a pin 16 which provides a fulcrum for anr I operating lever. 17, said lever being mounted-on the pin 16 between said links and is provided with a toe portion 18 there adjacent. I l The horizontal portion 12 of the band and 11 is provided on its inner end with a U-shaped;

engage the counter-sunk portion 4a of the head 4, the opposing walls ofsaid bracket supporting a rivet or pin 20, said bracket being for the reception of the swinging ends of the links 15 when the band 9 is being contracted; T l In -mounting the securing band 9 over the flange 6 of the head 4 and the bead 3 of the con- -4 tainer, the lever 17 and the links115- connected.% therewith, are swung to'the positionshown-zin full linesin Figs. 3 and 4. This released position ofthe lever 17 provides forv the band 9 to be ,ex-

theband canbe aptly and readily mounted in position over the flange of the head and the bead, of the chime of the container. After the band. has been mounted in position as just described, 1 and as securing bands of this character will be made in sizes to accommodate differentsizesof containers, the lever 17 is engaged and swung. with the links 15 on the pin 14, downwardly towards the bracket 19, and the toe portion-18, is engaged; on the far side ofthepini20 ,ofathei 5 l bracket as shown by dotted lines in Fig. 3. The lever 1'7 is then swung on the pin 16 of the links 15 and the toe portion 18 of the lever will be forced to ride under the pin 20 of the bracket 19 and the pin 20 will be seated in the dwell recess 21 of the lever 17, the toeing action of the portion 18 on the pin 20 of the bracket, drawing theends 11 and 10 of the band 9 towards each other thereby contracting theband.

Continued .downward swinging movement of the lever 17 will draw and lower the links 15 to a position in the bracket 19 until the alined re-.--;

cesses 22 on the lower edges of said links will ride in over-engagement with-the pin 20 of the bracket 19, and in this positionofengagement'ofthe recesses 22 of said links with therein-20, the lever 17 will have been lowered to a horizontal position, and the engagement" of -the links 15 with the pin 20 will provide a lock against as;

By; reason.- of the'operating mechanism being secured at rightang'les to the top side ofthe ba1'1d29; the, actuating effort will be: directlyagainst andion top of the bandfand :inaproperdirection for. forcing the band downwardly over theibeadr3 'ofi the. container chime, thereby as sisting the creeping or drawing action require'd inacontracting or drawing-the bandin securing position;

For removing the band 9 from its securing po-- sition overithe container chime and head-the sealing wire 28 is broken-and the lever-1'7 is swung upwardly tothe position shown in fulllines' in Fig. During the upward swing-of the lever 1'7 on the pin 16 of the links 15 for expanding the band for removaLthe toe portion 18' of said lever willibe first caused to [engage the bottomofthebraoketf19iandithus force or pry the-ends of the li-nks1'15 where they connect atl6 to said lever, upwardly, and dis-engage the recesses 22 I thereof from:the pin'20 of'the bracket 19in the manner asasli'own in Fig. 8; i
